this is pretty much what i was (am) thinking too :)

the logic's too complex to get right in different places without sharing. 
i'd like to pull out all the logic into an abstract superclass which will 
call expressXXX type methods. this should make it easier to implement 
other ways of output since it should be clear which methods are required. 
i agree that the signatures will be probably change a lot once we start 
looking at different implementation but hopefully they'd give us some sort 
of basis to start with.
